Effect of Anesthesia in Fracture Healing

Overview

Investigator' s study designed to investigate effect of general and regional anesthesia on fracture healing.The 40 age and older ASAI-III patients who will operate due to femur fracture (except femur neck fracture) will be enrolled in this study after informed consent approval. Subjects will be divided into two groups by a computerized randomization method. 40 patients will be enrolled in this study. General anesthesia will perform for 20 patients. Regional anesthesia will perform for 20 patients. Preoperative, 4. week and 12. weeks laboratory test which include blood and urine β-C terminal telopeptid (β-CTX), blood alkaline phosphatase and osteocalcin will test for all patients. All patients will not use nonsteroid anti-inflammatory drugs during study neither perioperative nor postoperative periods. fracture healing will be asses with clinical evaluation and laboratory tests.

Investigator' s study designed to investigate effect of general and regional anesthesia on fracture healing.The 40 age and older ASAI-III patients who will operate due to femur fracture (except femur neck fracture) will be enrolled in this study after informed consent approval. Subjects will be divided into two groups by a computerized randomization method. 40 patients will be enrolled in this study. Each group will have 20 patients. However a pilot study will perform for each groups with 10 patients. In Group G, all patients will be applied general anesthesia and 2 mg/kg propofol and 0,6 mg/kg rocuronium will administer to patients for induction of anesthesia. Maintenance of anesthesia will be made with %50-%50 O2/N2O and %2 sevoflurane. 0,1 mg/kg morphine will be held on last 10 minutes of operation for postoperative analgesia. Also, patient controlled analgesia with morphine(1 mg bolus and 20 min lockout time) will apply for postoperative analgesia. If it is necessary additional analgesic will provide with 100 mg peroral and intravenous tramadol. Regional anesthesia will perform for 20 patients which named Group R. In Group R combined epidural-spinal anesthesia will perform. Spinal %5 bupivacain 15 mg and 20µg fentanyl will apply and analgesia will provide with epidural bupivacain. Preoperative, 4. week and 12. weeks laboratory test which include blood and urine β-C terminal telopeptid (β-CTX), blood alkaline phosphatase and osteocalcin will all patients. All patients will not use nonsteroid antiinflammatory drugs during study neither perioperative nor postoperative periods. Fracture healing will be asses with clinical evaluation and laboratory tests. All measurements will be assessed with statistically.
